Merits of the Helpers in Madinah (Ansaar)

Bukhari :: Book 5 :: Volume 58 :: Hadith 234

Narrated Aisha:

The Prophet engaged me when I was a girl of six (years). We went
to Medina and stayed at the home of Bani-al-Harith bin Khazraj.
Then I got ill and my hair fell down. Later on my hair grew (again)
and my mother, Um Ruman, came to me while I was playing in a swing
with some of my girl friends. She called me, and I went to her, not
knowing what she wanted to do to me. She caught me by the hand and
made me stand at the door of the house. I was breathless then, and
when my breathing became Allright, she took some water and rubbed
my face and head with it. Then she took me into the house. There in
the house I saw some Ansari women who said, "Best wishes and
Allah's Blessing and a good luck." Then she entrusted me to them
and they prepared me (for the marriage). Unexpectedly Allah's
Apostle came to me in the forenoon and my mother handed me over to
him, and at that time I was a girl of nine years of age.
